TableLayoutPanel scroll bar issues
Hi .
I am using a table layout panel with autoscroll = true
I found several issues which dont seem to work properly
1. when I have more rows then in view and the vertical scroll bar is added
it sometimes also adds the Horizontal scroll bar because it doesnt adjust the
width properly and the scrollbar takes up part of the client area. This isnt
consistent, sometimes the horizontal appears and sometimes it doesnt .
2. I have noticed something funny . I want to remove and add a control and
while doing that I want to maintain the scroll position so I do
int prevVal = m_TableLayoutPanel.VerticalScroll.Value;
.... ADD AND REMOVE
m_TableLayoutPanel.VerticalScroll.Value = prevVal;
The funny thing is that if I call athe above line once it doesnt change the
VerticalScroll.Value . IF I call it TWICE then the second time it does change
the Value.
so my code looks like this
m_TableLayoutPanel.VerticalScroll.Value = prevVal;
m_TableLayoutPanel.VerticalScroll.Value = prevVal;

System.ComponentModel.Win32Exception: Error creating window handle.
Hi All,
I am using WinForm and .NET 2.2 framework in my application. My application
mainly uses Infragistics WinGrid. I am extending infragistics grid to
support some functionality by adding winform's toolstrip control (which
intern hosted in a User Control) on Grid Headers. The way I extend this grid
is by implementing Infragistic's IUIElementCreationFilter interface. This
interface provides two methods, AfterCreateChildElements and
BeforeCreateChildElements. The issue that I am facing is, when I load grid,
I am getting following error and it kills my application.
"System.ComponentModel.Win32Exception: Error creating window handle".
This error occurs only when I set BackColor property of my user control to
Transparent. If I do not set BackColor or set it to some color my
application just works fine. I checked the number of window handles and also
GDI Object count at the time this error is thrown. Window handle count is
around 500 and GDI Object count is around 125. Also this error does not
occur all the time. In my application I have several modules where I use
infragisitcs WinGrid which in tern calls same implementation of
IUIElementCreationFilter interface and the code work fine for other modules.
I am not able to figure out as to why this issue is occurring sometimes and
what is that causing it.
During my investigation I found that adding user control with BackColor =
Transparent into Grid's control collection invokes OnPaint event handler and
which intern calls AfterCreateChildElements method in recursive way.
AfterCreateChildElements method is called after an element's ChildElements
have been created. The child element's can be repositioned here and/or new
element's can be added.

complicated forms design
How others have approached having extremely large forms that duplicate
database structures.
I am currently designing an application with a lot of tables and a lot of
controls. Problem is that the forms are very much overloaded and
therefore my basic structure is very wrong.
I have about 40 database tables, a few forms, multiple tabs on each with
moderately complicated layout on each tab. You can imagine the whole
design, number of events, and how it ends up.
How have others managed this sort of complicated design?
Do you break off the database into a separate class, how can you keep
this visual?
Can you layout a tab on its own visually and then embed in the actual
form at runtime.

Changing the Form Default BackColor at Runtime
I have a program that have over 10 forms in it. The BackColor for each form
defaults to System.Drawing.SystemColors.Control.
How can I override or change what that color is? Basically what I would

having to program each and forms/controls in the application.
How can I build a new color pallete that will override the SystemColors

ObjectDisposedException
Hi,
I have an invisible button in my form. I have a timer
(System.Windows.Forms.Timer) with interval 300 ms. In the timer tick event I
check for a certain flag, and if that flag is true, the button becomes
visible (After setting the flag's status to false again).
The problem is that if the event happened and the button became visible, and
then I closed the form, and then reopened it and let the event happen again,
then the operation of making the button visible throws an exception of type
System.ObjectDisposedException.
It looks like when I reopen the form, I already haven't got the button. One
could think it's been Garbage Collected, but I'm not sure about that, because
the button is part of the form which is reopened (Form f = new Form(); ).
Can someone please explain the source of the problem and the solution?

Strange modal form behaviour
Hi guys, it's a little problem but I'm quite stuck with it. I'm
developing a Windows Forms application with VS2008 and I have noticed
this little graphical bug. I have a main form with ShowInTaskbar=true.
I open a modal form (with showdialog()) with ShowInTaskbar=false.
Then, just sometimes, when a use the "Show Desktop" icon or I change
the active program when I go back to mine I can see just the main form
(the modal form is somehow hidden) and obviously it's locked, I can't
interact with it. Neither I can see use the modal form because it's
hidden, so I have to change the active program with ALT+TAB and the go
back to my application. With this move I can get back my modal form
and can continue working. How can I avoid this and keep my modal form
"hidden" from the taskbar?

Application exiting before doing what it should do
Hi

alert does not get time to be displayed. However the same alert displays
fine if I use start-up form (instead of SUB Main) and use a button on form
to run the ShowDesktopAlert SUB.
What is the problem and how can I make it work using SUB Main?

DataGridView and ThreeState
Hello,
I have a DataGridView with a DataGridViewCheckBoxColumn. I want to be
able to have the checkbox display in an indeterminate state, so I've
set the ThreeState property to True. However, I want the indeterminate
state to only be set programatically - whenever the user clicks the
checkbox, it should only toggle between Checked and Unchecked.
Now, this is the default behaviour of a standard CheckBox control - as
detailed in the CheckBox.ThreeState property documentation:
"the CheckState property value can only be set to the Indeterminate
value of System.Windows.Forms.CheckState in code and not by user
interaction"
How would I achieve this with DataGridView? I'm committing the changes
to the checkbox cells immediately by catching the
CurrentCellDirtyStateChanged event and calling CommitEdit as suggested
in the documentation for DataGridView. However, if I try catching the
indeterminate state in this event or in CellValueChanged, and setting
Value to CheckState.Unchecked, the cell's Value property changes but
the display does not update until the control loses focus or another
row is selected.
As this is the default for the CheckBox control, I'm sure it can't be
that difficult to get the DataGridView to do it. What am I missing?
Thanks in advance for your help,

ClickOnce on a Terminal Services server farm
Hello,
I think I know the answer to this, I would just like a second opinion
and other ideas.
We have a ClickOnce application that one of our clients would like to
install in a Terminal Services server farm. The application is
installed from a URL and added to the Start menu and uses the .NET 2.0
framework.
The ClickOnce application files are stored in the directory
C:\Documents and Settings\<username>\Local Settings\Application Data.
The issue is that the Local Settings folder is not part of Profile
Synchonization (or folder redirection). Their policy is that files in
the Local Settings folder are removed when the user logs off. The
result is that the application is re-installed each time the user runs
the application from the start menu. This is of course unacceptable.
I am afraid that the only solution is to have them use an MSI file,
but I am looking for other ideas?
I have read conflicting reports that there is a way to modify the
ClickOnce store on each server? Anyone?
Thanks in advance.

DoubleBuffered not working in panel?
For a kiosk-type application I have a form with some labels placed directly
onto it, and an empty panel that covers part of the form.
During program execution, labels are added to and removed from that panel
to display different information.
The form has a background image.
Its DoubleBuffered property = True to avoid flickering during updates, but
double buffering seems to be used only for controls placed directly on the
form, not for those within the panel. Updating the panel without visible
flicker seems to be impossible.
Each "flicker" consists of the background image within the panel's
boundaries first disappearing (replaced by the form background color), and
reappearing immediately thereafter.
When the background image reappears, that doesn't happen in a single
stroke: it becomes visible first for about half of the area. The rest
follows at the next display refresh (I mean monitor vertical sync).
If you ask me, this (disappearing / reappearing in more than one display
refresh) means it is either not being double-buffered, or the working
buffer is copied into the screen buffer to soon, while it is still being
repainted.
The platform is XP Professional (application being developed for later use
on XP Embedded).
The flicker does NOT seem to occur on my development machine, which is
running Vista, but this machine is also equipped with a more performant
processor and display adapter, which may explain the difference too. Tag: Microsoft Report Viewer Control Tag: 117578
Newbie question: Cstr vs toString
Hi
I have a WinForm app with a bound form. When user enters a value in field
rateid I lookup the respective rate amount from a table and assign it to
field rate.I am using the DLookup function to achieve this (full code given
below). This function returns a value of type object so I need to convert it
to string. If I use the function as below (using ToString) it works fine;
Me.txtRate.Text = DLookup(<parameters here>).ToString
but if I use it with a CStr
Me.txtRate.Text = CStr(DLookup(<parameters here>))
and then browse through 2-3 record the form stops showing data in the bound
fields. This brings me to question; what is the difference between CStr and
tostring that could be causing the above problem?
Thanks

Compatible Type for DataGridViewRowCollection + 'SelectedRowCollec
Good afternoon (for everyone in time zones -10 through +1, at the moment).
This is a minor problem, but it's bugging me, it seems like there should be a
graceful solution.
I need to iterate over either the selected rows in a DataGridView, or (if
none are selected) ALL the rows. Either way I perform the same operations.
At the moment, I have a switch leading to one of two foreach loops, each with
identical content. What I'd like to do is choose one of two collections
(.Rows or .SelectedRows) and then iterate over it - no repeated code.
However, the types of these parameters are DataGridViewRowCollection and
DataGridViewSelectedRowCollection rather than IEnumerable<DataGridViewRow>.
The docs say that they implement this interface, or rather implement
IEnumerable, but it's invalid to cast up. This is what I'd like to get
working:
IEnumerable<DataGridViewRow> rows =
DataContacts.SelectedRows.Count == 0 ?
DataContacts.Rows : DataContacts.SelectedRows;
foreach (DataGridViewRow row in rows)
/*Do stuff with the row*/
This fails at compile time; casting .Rows and .SelectedRows to
IEnumerable<DataGridViewRow> fails at runtime. This is my inelegant
workaround:
if (DataContacts.SelectedRows.Count == 0)
{
foreach (DataGridViewRow row in DataContacts.Rows)
/*Do stuff with the row*/ }
else
{
foreach (DataGridViewRow row in DataContacts.SelectedRows)
/*Do stuff with the row*/ }
Any thoughts? I suppose could wrap the "Do stuff" part in a function, or
use a delgate, but it seems clumsy. Thanks! Tag: Microsoft Report Viewer Control Tag: 117566
Icon size in listview
Hi,
When the user drags an icon in the listview, i want to prevent him
from dropping
the icon such that it overlapps with another icon. Therefore i need to
know the size
of the icons. Is there a way to know the size?
Thanks,

Lookup in gridview
Hi
I have a gridview bound to a backend table A via dataset/data adapter. A
drop down is bound to a second table B. When user selects a value form drop
down I want to lookup another column in table B based on value selected from
drop down and assign the lookup value to a column in gridviw. How can I pick
the value selected by user and do the lookup from table B?

ClickOnce installs to Vista Client
I have placed a ClickOnce installation package on a Windows 2003 server. I
am able to install from this location to a Windows XP client. However, when
I attempt to install to a Vista client, the installation is unsuccessful.
The log shows the error message "Unable to connect to the remote server. No
connection could be made because the target machine actively refused it."
Vista has no problem obtaining and displaying the publish.htm page, so I
know this client has access to the server. The server is capable of serving
up the install properly to an XP client, so I think the server is configured
properly. So what needs to be changed so I don't get this error on a Vista
client? Tag: Microsoft Report Viewer Control Tag: 117555
Impact of Verisign Timestamping Service on ClickOnce deployed Apps
We have a number of applications that are deployed using ClickOnce and we use
the VeriSign timestamping service. The VeriSign timestamping service is being
upgraded to use SHA-1 instead of MD5 and I need to gauge how this will affect
our applications.
From what I understand when the application is signed the TimeStamping
Service is called to generate a hashed timestamp that is inserted in the code
with the signature. When the client verifies the signature it verifies the
timestamp and if it is valid it ignores the expiration date of the
certificate.
This means that nothing should change on the deployment side but it will
affect client machines with older operating systems (Pre Win2k) that don't
know how to deal with SHA1 timestamp.
Can anyone confirm this information and tell me if any other problems await
me? Tag: Microsoft Report Viewer Control Tag: 117554
class libraries and components
I'm posting here rather than in the controls group because mine is a
multi-part question, only partially involving components. It's more a
design issue. The environment is VS2008, BTW.
I am a long-time C++ MFC consultant (who also does native code
Delphi), stepping temporarily into the dotnet world to solve a
specific problem. For our new system I have developed a communications
interface, the details of which need not concern us here. Suffice it
to say that you talk to this beast via a DLL, using messages in a
fixed (binary) format. That works fine for the C++ server apps. But C#
client-side programs will now also need to talk to this interface.
Obviously the C# message objects have to be marshalled into this
binary format. I already have the code to do a subset of the necessary
marshalling developed for an earlier prototype which talked to an
older version of the comms utility, using the old obsolete DDE format
(it used the NDDE DLL that some kind soul published). That code was
standalone classes within a single project. Now I need something that
can be shared among multiple developers.
So in essence, I have a bunch of classes to represent the messages,
which C# apps need to use, and a bunch of functions which implement
the DLL interface, which C# apps also need to use, passing the one
into the other.
For the sake of simplicity, it seems to me that the connection to the
comms subsystem should be handled via a component which C# developers
can just drop onto their form. This would be a non-visual component,
which would encapsulate the DLL interface. I then thought that the
classes would form an ordinary class library... but it seems like the
only way for multiple C# apps to share code is via a referenced
assembly. There seems to be no equivalent of a simple shared unit of
code, like a Delphi unit.
Also, because of the interop issues, for a C# app the DLL interface
only makes "sense" when viewed via the classes implemented in the
class library, so it looks like the classes really belong inside the
component. C# apps certainly can't send the binary format that the DLL
expects, so the component needs to do the marshaling as well.
I am _really_ lost in this alien enviroment. Can anyone offer advice,
or point me at a good book/site on component authoring?

The wish to pass a value from a (child) class to a (parent) form
I have a MainForm class and a second class which initializes an

This is just a simplified representation of the MainForm class:
partial class MainForm : Form

Application.Run(new MainForm());
}
// Public accessor
public string textToDisplayBox
{
set { this.textBox4.Text = value; }
}
// CommunicationManager
CommunicationManager comm = new CommunicationManager();
}
The CommunicationManager class has a simple function, i.e. to collect
in a string the output from the comport...
My troubles stem from the fact that I am unable to reference back to
the form which second class is initiated.
Do you have any suggestions on how to achieve this?

How to make it use 5th version of comctl32.dll
Hi,
For some reason my .NET application uses the 6th version of comctl32.dll and
not the 5th which, according to Microsoft, should also be present in
Windows. The new DLL is causing problems with my TreeView based control so I
want to go back to the 5th version of the DLL. How do I do that?
Also I am curios how did the user manage to get 6th version withouth the 5th
